I heard a story on NPR today about how new safety concerns affected one scientist's research on corona viruses. The fear is that scientists may make viruses more contagious and therefore dangerous to people in the event the viruses escape the laboratory, so the U.S. government halted funding of some research pending further review. From the transcript:
But [virologist] Baric says, when it comes to SARS and MERS, there are key differences between people and mice.
"No. 1, mice don't sneeze," says Baric, so they don't transmit these diseases through the air. And he says the process of adapting these viruses to mice actually makes the germs less able to infect human cells.
I was very surprised to learn that mice do not sneeze. A Google search produces video of a mouse supposedly sneezing plus many articles and blog posts about sneezing mice and what you can do to help them.
Who's right? Do mice sneeze?
